Embodiment 1

[0014] An additive composition for water tank antifreeze, made of the following compositions in parts by weight:

[0015] 3 parts of borax, 10 parts of sodium phosphate, 5 parts of potassium dichromate and 6 parts of ethylene glycol monomethyl ether, prepared by simple mechanical mixing.

Embodiment 2

[0017] A water tank antifreeze, made of the following compositions in parts by weight:

[0018] 15 parts of auxiliary agent composition (prepared in Example 1), 30 parts of deionized water, 12.5 parts of ethylene glycol, 8.5 parts of phthalic anhydride, 7 parts of butyl acetate and 2 parts of Xanthophylla glabra.

[0019] A preparation method of water tank antifreeze, the steps are as follows:

[0020] First, add 15 parts of additive composition and 30 parts of deionized water to the stirring container, control the speed at 800 r / min, and stir for 1 h; then add 12.5 parts of ethylene glycol and 8.5 parts of phthalic anhydride, control the speed at 900 r / min, stirring for 1 h; finally, add 7 parts of butyl acetate and 2 parts of Xanthophyllin, control the rotation speed at 500 r / min, and stir for 2 h to obtain the antifreeze solution for the water tank.

Abstract

The invention relates to the technical field of an anti-freezing solution, and in particular relates to a water tank anti-freezing solution. The water tank anti-freezing solution is prepared from the following compositions in parts by weight: 15 parts of aid compositions, 30 parts of deionized water, 12.5 parts of ethylene glycol, 8.5 parts of phthalic anhydride, 7 parts of n-butyl acetate and 2 parts of nitidine. Due to reasonable design of the components and ratio of the water tank anti-freezing solution, the product quality of the anti-freezing solution can be improved by about 30%. Meanwhile, because the raw material selection of the aid compositions is reasonable, the product value of the anti-freezing solution can be further improved.

Description

technical field [0001] The invention relates to the technical field of antifreeze, in particular to a water tank antifreeze. Background technique [0002] At present, the antifreeze used for water tanks on the market basically fails to meet the performance requirements of antifreeze. Therefore, it is necessary to redesign the components, proportions and preparation methods of an antifreeze for water tanks. Contents of the invention [0003] The object of the present invention is to provide a kind of water tank antifreeze and preparation method thereof, and the auxiliary agent composition for water tank antifreeze. In order to achieve the above object, the present invention adopts the following technical solutions: [0004] An additive composition for water tank antifreeze, made of the following compositions in parts by weight: [0005] 3 parts of borax, 10 parts of sodium phosphate, 5 parts of potassium dichromate and 6 parts of ethylene glycol monomethyl ether, prepared ...
